Supported Functions

This is a list of TeX functions supported by KaTeX. It is sorted into logical groups.

There is a similar Support Table, sorted alphabetically, that lists both supported and un-supported functions.

a'

环境

\begin{matrix} a & b \\ c & d \end{matrix}

KaTeX also supports darray and dcases.

Acceptable line separators include: \\, \cr, \\[distance], and \cr[distance]. Distance can be written with any of the KaTeX units.

The {array} environment supports | and : vertical separators.

The {array} environment does not yet support \cline or \multicolumn.

Notes:

distance will accept any of the KaTeX units.

\kern, \mkern, \mskip, and \hspace accept unbraced distances, as in: \kern1em.

\mkern and \mskip will not work in text mode and both will write a console warning for any unit except mu.

where:

F = (font size of surrounding HTML text)/(10 pt)

G = 1.21 by default, because KaTeX font-size is normally 1.21 × the surrounding font size. This value can be overridden by the CSS of an HTML page.
